Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Aqueous Zn‐ion batteries (AZIBs) are expected to become one of the most promising candidates for large‐scale energy storage, but are impeded by uncontrollable dendrite growth and parasitic reactions. In this study, we propose a simple mechanical shot‐peening (SP) approach for restructuring commercial Zn foils into highly exposed (002)‐textured

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT The use of Ti6Al4V alloy in dental implantation is constrained by its high elastic modulus and biological inertness, which lead to delayed osseointegration and a high failure risk. Additionally, its chemical incompatibility with hydroxyapatite (HA) impedes the development of stable bioactive composites.

GATA4在肝癌细胞中的表达及其对肝癌细胞增殖、迁移和侵袭能力的影响
Zhongguo shiyan zhenduanxue, 2019 目的探索转录因子GATA4在肝癌细胞系中的表达及其表达改变对肝癌细胞增殖、迁移和侵袭能力的影响。方法通过RT-PCR和Western Blot检测正常肝细胞、肝癌细胞系的表达,在体外构建GATA4基因沉默和过表达模型,分析并比较转录因子GATA4表达变化对肝癌细胞增殖、迁移和侵袭的影响。结果 GATA4mRNA在肝癌细胞系(SMMC7721、Hep3B)中高表达,在正常肝细胞HLLP-7702和HepG2中低表达,GATA4蛋白在正常肝细胞(HL-7702)和肝癌细胞系(SMMC7721 ...
